Install build system

Before we can build the NextEuropa platform we need to install the build system itself. This can be done using composer:

$ composer install

Customize build properties

Create a new file in the root of the project named using your favourite text editor:

$ vim

This file will contain configuration which is unique to your development machine. This is mainly useful for specifying your database credentials and the username and password of the Drupal admin user so they can be used during the installation.

Because these settings are personal they should not be shared with the rest of the team. Make sure you never commit this file!

All options you can use can be found in the file. Just copy the lines you want to override and change their values. For example:

# The location of the Composer binary.
composer.bin = /usr/bin/composer

# The install profile to use. = multisite_drupal_standard

# Database settings. = my_database
drupal.db.user = root
drupal.db.password = hunter2

# Admin user.
drupal.admin.username = admin
drupal.admin.password = admin

# The base URL to use in Behat tests.
behat.base_url = http://nexteuropa.local

Listing the available build commands

You can get a list of all the available Phing build commands ("targets") with a short description of each target with the following command:

$ ./bin/phing

Building a local development environment

$ ./bin/phing build-platform-dev
$ ./bin/phing install-platform

From the release 2.4.x following configuration variables are available:

  • The default theme to enable, set to either "ec_resp" (default) or "ec_europa". = ec_resp

  • The default Europa Component Library release which is used to build the EC Europa theme.

ecl.version = v0.10.0

  • The default EC Europa theme release version.

ec_europa.version = 0.0.2

  • The default Atomium theme build properties. Used only if default theme is set to "ec_europa". You can find default values of those variables below.

platform.theme.atomium.repo.url = platform.theme.atomium.repo.branch = 7.x-1.x

Building a local development environment for the EC Europa theme

There is a specific Phing target which is setting up the development environment for the EC Europa theme needs. It helps developers to perform code reviews and contribute code to the repositories. It clones the repository of the Atomium and EC Europa themes. It will also fetch the release package of the Europa Components Library and regenerate theme assets.

To run this target you must have node.js and npm installed on your local machine. You need also configure additional configuration variables which are described in the section above. The most important is to set the variable to ec_europa.

You can use this Phing target in the following way:

$ ./bin/phing build-europa-dev

This Phing target is meant to be used only for the local development purposes.

Generic users.

After install, generic users are created. Login using drush user-login command.

$  cd ./build
$  drush uli

And setup a new password for these users.

Running Behat tests

The Behat test suite is located in the tests/ folder. When the development version is installed (by running ./bin/phing build-platform-dev) the Behat configuration files (behat*.yml) will be generated automatically using the base URL that is defined in

If you are not using the development build but one of the other builds (build-platform-dist or build-multisite-dist) and you want to run the tests then you'll need to set up the Behat configuration manually:

$ ./bin/phing setup-behat

In order to run JavaScript in your Behat tests, you must launch a PhantomJS instance before. Use the --debug parameter to get more information. Please be sure that the webdriver's port you specify corresponds to the one in your Behat configuration (behat.wd_host.url: "http://localhost:8643/wd/hub").

$ phantomjs --debug=true --webdriver=8643

If you prefer to use an actual browser with Selenium instead of PhantomJS, you need to define the Selenium server URL and browser to use, for instance:

behat.wd_host.url = http://localhost:4444/wd/hub = chrome

The tests can also be run from the root of the repository (or any other folder) by calling the behat executable directly and specifying the location of the behat.yml configuration file.

Behat tests can be executed from the repository root by running:

$ ./bin/behat -c tests/behat.yml

The platform can run 4 different behat profiles:

  • default: it runs behat tests against a multisite_drupal_standard build using the "Europa" theme;
  • communities: it runs behat tests against a multisite_drupal_communities build using the "Europa" theme;
  • standard_ec_resp: it runs behat tests against a multisite_drupal_standard build using the "ec_resp" theme;
  • communities_ec_resp: it runs behat tests against a multisite_drupal_communities build using the "ec_resp" theme;

The behat execution command mentioned above runs the tests only with the default profile.
The tests will fail with it if the platform is built with the "ec_resp" theme.

To run a profile other than the default one , the following command must be executed:

$ ./bin/behat -c tests/behat.yml -p [profile]

[profile] stands for the profile name as written in the list above; I.E: communities, standard_ec_resp, communities_ec_resp.

If you want to execute a single test, just provide the path to the test as an argument. The tests are located in tests/features/. For example:

$ ./bin/behat -c tests/behat.yml tests/features/content_editing.feature

Some tests need to mimic external services that listen on particular ports, e.g. the central server of the Integration Layer. If you already have services running on the same ports, they will conflict. You will need to change the ports used in

Remember to specify the right configuration file before running the tests.

Running PHPUnit tests

Custom modules and features can be tested against a running platform installation by using PHPUnit. When the development version is installed (by running ./bin/phing build-platform-dev) the PHPUnit configuration file phpunit.xml will be generated automatically using configuration properties defined in

If you are not using the development build but one of the other builds (build-platform-dist or build-multisite-dist) and you want to run PHPUnit tests then you'll need to set up the PHPUnit configuration manually by running:

$ ./bin/phing setup-phpunit

Each custom module or feature can expose unit tests by executing the following steps:

  • Add registry_autoload[] = PSR-4 to
  • Create the following directory: YOUR_MODULE/src/Tests
  • Add your test classes in the directory above

In order for test classes to be autoloaded they must follow the naming convention below:

  • File name must end with Test.php
  • Class name and file name must be identical
  • Class namespace must be set to namespace Drupal\YOUR_MODULE\Tests;
  • Class must extend Drupal\nexteuropa\Unit\AbstractUnitTest

The following is a good example of a valid unit test class:


 * @file
 * Contains \Drupal\nexteuropa_core\Tests\ExampleTest.

namespace Drupal\nexteuropa_core\Tests;

use Drupal\nexteuropa\Unit\AbstractUnitTest;

 * Class ExampleTest.
 * @package Drupal\nexteuropa_core\Tests
class ExampleTest extends AbstractUnitTest {

PHPUnit tests can be executed from the repository root by running:

$ ./bin/phpunit -c tests/phpunit.xml

Running Drupal Simpletests on the platform

Check the documentation here

Checking for coding standards violations

After executing the 'setup-php-codesniffer' Phing target, PHP CodeSniffer will be set up and can be run with the following command:

# Scan all files for coding standards violations.
$ ./bin/phpcs

# Scan only a single folder.
$ ./bin/phpcs profiles/common/modules/custom/ecas

Docker-compose.yml file

Our developement environment already provides a docker-compose.yml file. It can be found on


Make file patches

Make file patches are added to contributed modules while building the platform, just after the contributed modules gets downloaded.

Composer patches

Composer patches are added via cweagans/composer-patches to projects via composer.json.
